Whole Number Subtraction Using a Number Line

This video tutorial explains how to perform whole number subtraction using a number line. It introduces the terms 'minuend', 'subtrahend', and 'difference', and demonstrates subtraction with examples: 7 - 5, 12 - 8, and 22 - 14. Each example is illustrated by moving along a number line, showing how to decrease the minuend by the subtrahend to find the difference.
